Ok for the last few years i’ve really struggled with hum from my monitor speakers.
It was much worse on my windows machine and it’s much better now I have an iMac.
Having said that I just don’t understand whats going on.
When I first fire up my speakers everything is silent and lovely!
If I have the speakers on (30 minutes-1 hour-2 hours-all day) i’ll get a gradual speaker hum buzz & hiss.
I don’t get any of the electrical interference, like squeaking and computer talk I used to get on my windows machine which is great.
It’s just a clean “buzzzzzzzzzzzz” sound that overtime suddenly becomes the loudest thing around my desk space.
the interesting thing is that if I turn the speakers off for a good amount of time,maybe half and hour I can then turn them back on ,and for a short amount of time not get the buzzing.
I just wondered if anyone knew how to perhaps eradicate the noise or could explain the science of whats going on and why the noise is there after a short period of time but not when I turn them on initially.
My setup is as follows.
KRK Rokit RP6 , both set to about -20db gain, both plugged into a electrical extension that is designed to eliminate electrical noise.
